Abstract
Description
- This invention pertains to a system for the management and routing of cables, such as telecommunications cables. More particularly, this invention pertains to flexible enclosure assemblies for cable management systems.
- In the telecommunications industry, the use of optical fibers for signal transmission is accelerating. With the increased utilization of optical fiber systems, optical fiber cable management requires industry attention. Similar issues exist with other telecommunications cables such as copper-based cables.
- One area of telecommunications cable management that is necessary is the routing of cables from one piece of equipment to another. For example, in a telecommunications facility, optical fiber cables may be routed between fiber distribution equipment and optical line terminating equipment. In buildings and other structures which carry such equipment, the cable routing can take place in concealed ceiling areas or in any other manner to route cables from one location to another. Accordingly, such routing systems often include a plurality of trough or enclosure members, fittings and couplings for routing the cables. U.S. Pat. Nos. 5,067,678; 5,316,243; and 5,752,781 show various cable routing systems.
- When routing cables, it is desirable that the routing system will be easy to install. For example, providing a continuous cable path throughout the system can be a challenge, such as when obstacles or misalignments arise during installation of the system. There is a need for devices which make system installation easier and less reliant on precisely aligned components. There is a need for an improved, simplified, cost effective system for making adjustments in the alignment of a cable management system.
- The present invention relates to a flexible cable guide member and assembly. The assembly includes first and second cable guide members having a curved wall with open ends. The curved walls define first and second cable pathways respectively for receiving a telecommunications cable. A first end of the first guide member defines a socket. A second end of the second guide member is rounded to be received by the socket of the first guide member to produce a ball-and-socket joint between the first and second guide members. The second guide member is snap-fit into the socket of the first cable guide member. The guide members define longitudinal slots to allow cables to be added or removed from the assembly. The first and second guide members are preferably identical.
- Another aspect of the present invention relates to the method of retaining cables inside a cable guide assembly. The method includes the step of twisting or rotating one cable guide member relative to another so that longitudinal slots through each guide member no longer overlap, thereby enclosing the cables.
- A variety of advantages of the invention will be set forth in part in the description that follows, and in part will be apparent from the description, or may be learned by practicing the invention. It is to be understood that both the foregoing general description and the following detailed description are explanatory only and are not restrictive of the invention as claimed.

- While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail below. It is to be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the invention is intended to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.
- In the following detailed description, references are made to the accompanying drawings that depict various embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized, and structural and functional changes may be made without departing from the scope of the present invention.
- Referring now to FIGS.1-3, a flexible
cable management assembly 100 according to the present invention is shown. Theassembly 100 includes a plurality ofcable guide members 110 consecutively linked between twocable guide adapters guide member 110 receives an adjacent guide member and, in turn, is received by anadjacent guide member 110. Together the linkedguide members 110 define a combined cable pathway 116 along a central, longitudinal axis. - Referring now to FIGS.4-8, each
guide member 110 includes acurved wall 118 having openopposite ends curved wall 118 defines alongitudinal cable pathway 126 for receiving at least one telecommunications cable. Thecurved wall 118 also defines alongitudinal slot 124 or opening between the twoends slot 124 allows cables to be placed inside or removed from thecable guide member 110. Aflange 119 extends outwardly fromend 120. -
Guide members 110 are generally shaped as an hourglass having a narrow middle portion 111 between to wider ends 120 and 122.End 120 defines asocket 128 for receivingadjacent guide members 110. The curved walladjacent end 122 is rounded in the shape of a spherical zone corresponding to the size ofsocket 128 so thatend 122 can be received by thesocket 110 of an adjacentidentical guide member 110. When end 122 of afirst guide member 110 is received into thesocket 128 of asecond guide member 110, a ball-and-socket joint is formed. The ball-and-socket joint allows the second guide member to be angled relative to the first guide member in two perpendicular directions. It is to be understood thatend 122 andsocket 128 may include gaps and openings such aslongitudinal slot 124 and still fall within the scope of the invention. - To retain
end 122 withinsocket 128,retention tabs 130 having rampedsurfaces 132 extend from an inside surface of thecurved wall 118near end 120. The ramped surfaces 132 allow twoguide members 110 to be snap-fit together. - An outside surface of
curved wall 118 includes adetent bump 134near end 122.Socket 128 includes first andsecond detent grooves Detent bump 134 may be received in eitherdetent groove end 122 is received insocket 128. FIG. 9 shows anassembly 200 of twoidentical guide members 110′ and 110.Grooves guide member 110 are indicated by broken lines. The detent bump and groove arrangement maintains the axial rotational position ofguide member 110′inside guide member 110. That is,guide member 110′ can be rotated around its longitudinal axis 140 (see FIG. 8) relative to guidemember 110. Detent bump and groove arrangement establishes two stable positions in this dimension. Whenbump 134 is received infirst groove 136, slot 124′ is aligned with slot 124 (as shown in FIG. 9) allowing cables to be added or removed from theassembly 200. As shown in FIG. 10,guide member 110′ may be rotated about itslongitudinal axis 140 relative to guidemember 110 so thatdetent bump 134′ is received bygroove 138. In this position,slots assembly 100 shown in FIGS. 1-3, theguide members 110 are all rotationally positioned so that thelongitudinal slots 124 of each guide member are aligned. - As shown in FIGS.1-3,
many trough members 110 can be combined to produce a cable management assembly defining a curvilinear cable pathway. The ability to enclose the cable pathway by rotating theguide members 110 relative to one another, makes the assembly well suited for both vertical and horizontal applications. That is, the present invention is a efficient means of managing and guiding cables down from cable management systems suspended near the ceiling to lower telecommunications equipment. The present invention is also useful in correcting for misaligned cable management systems. Furthermore, theguide members 110 are versatile in that thesame guide member 110 may be used to angle the cable pathway in a variety of directions. This ability eliminates the need to manufacture and stock several different parts for each direction. Thecable guide members 110 are also versatile in that they can angle the cable pathway simultaneously in two perpendicular directions. - The
guide members 110 in accordance with the present invention can be assembled on-site to the desired length. This helps the installer by avoiding precise measurement of dimensions. The installer can order or stock a number oftrough members 100 separately or in kits and then assemble them together to define the desired length of trough. Further, because of the flexibility of the trough to define a variety of angles and shapes, the installer can conveniently link cable pathways without having to premeasure the offset or misalignment. - Another advantage of the present system is its ability to prevent damage to cables and signal transmission resulting from excessive bending. Excessive bending of a cable beyond a recommended minimum bend radius can result in degradation of the information signal being transmitted. Because each
guide member 110 of the present invention when mated to anotherguide member 110 can only angle the cable pathway a limited amount, the minimum bend radius of the cables can be maintained. - FIGS.11-14 show the first
cable guide adapter 114. Theadapter 114 has arectangular end 160 and acurved end 162.Curved end 162 defines asocket 164 similar tosocket 128 inguide member 110.Socket 162 is sized to receiveend 122 ofguide members 110.Adapter 114 also defines alongitudinal slot 166 along its length to allow cables to be added or removed from theadapter 114.Rectangular end 160 may be coupled to existing rectangular cable guides, such as cable guide downspouts, using any of various couplings known in the art.Adapter 114 includes threeopenings 168 spaced aroundadapter 114. Aledge 170 having a rampedsurface 172 defines one side of eachopening 168.Ledges 170 protrude into the interior of theadapter 114 and act in the same way asretention tabs 130 inguide members 110 to retainend 122 of a matedguide member 110 insocket 164. - FIGS.15-18 show the second
cable guide adapter 112.Adapter 112 has arounded end 174 and acylindrical end 176. Likeend 122 ofguide member 110,rounded end 174 ofadapter 112 is shaped as a spherical zone to be received by a socket such assocket 128 onguide member 110.Adapter 112 also defines alongitudinal slot 178 along its length to allow cables to be added or removed from theadapter 112.Cylindrical end 176 may be coupled to existing cylindrical cable guides, such as cable guide tubing, using any of various couplings known in the art. - With regard to the foregoing description, it is to be understood that changes may be made in detail without departing from the scope of the present invention. It is intended that the specification and depicted aspects of the invention may be considered exemplary, only, with a true scope and spirit of the invention being indicated by the broad meaning of the following claims.
